SWISS A220 Cancellations

Yesterday, a Swiss International Air Lines (SWISS) Airbus A220-300 (formerly Bombardier C Series CS300) suffered an In-Flight Shutdown (IFSD) of one of its Pratt & Whitney PW1524G engines, the third such IFSD in less than three months. In each case, the flight diverted and landed safely; post-flight investigations revealed a missing low-pressure compressor rotor stage 1 (LPC R1). An Airworthiness Directive (AD) had been issued on 26 September 2019, ten days after the second SWISS incident, mandating periodic inspections of the engines for cracks.

Following yesterday's incident, SWISS cancelled 30 of today's flights in order to carry out additional inspections. 21 of the cancelled flights touched the airline's main hub at Zürich while ten touch Geneva. (One of the cancelled flights was from Geneva to Zürich.)

Today's Featured Map shows the routes of the cancelled flights, with Zürich routes in red and Geneva routes in black.
